Calculating Beta vs Bitcoin

A few days ago a few friends asked me to calculate beta for several coins versus Bitcoin. Below is a 60 day beta calculation of a few alt coins against BTC. Now it probably makes sense to use a different proxy for the market instead of Bitcoin. A better solution would be to put together a weighted basket of currencies or using the CoinMarketCap total market instead. Feel free to use the code below. I use Plotly for my charting. I’ve never calculated before so I may be wrong in my approach. If you have feedback please let me know on Twitter or via email (contact@quantalys.us).
